RELATED APPLICATIONS

The present application is a Divisional of U.S. patent application Ser. No. 15/682,590 filed on Aug. 22, 2017, which claims priority from U.S. Provisional application No. 62/378,233 filed on Aug. 23, 2016, the disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to an integrated circuit for controlling sensors and more particularly to an integrated circuit that serves as a generic interface for controlling sensors by commands from a remote server, for example a cloud server.

BACKGROUND OF THE INVENTION

Many control systems use embedded integrated circuits for controlling sensors. The integrated circuits collect physical information, analyze the information and take actions in response to the analysis. For example a tracking device may have an embedded integrated circuit that accepts location measurements from a Global Navigation Satellite System (GNSS) and transmits the measurements over a mobile network to a user's mobile smartphone.

Likewise an irrigation system may include an embedded integrated circuit that is connected to sensors for determining soil conditions, temperature, water pressure and other details. The embedded integrated circuit analyzes the information from the sensors and activates irrigation based on the analysis. Similarly many other systems such as drones, cameras, pulse meters and the like also may include embedded integrated circuits.

Typically preparation of an embedded integrated circuit require extensive planning and is generally an expensive process. Additionally, if improvements are required or software errors are found it is generally complicated to upgrade the software, since every unit must be updated, for example by being reprogrammed, by replacing memory elements or by manufacturing a new version of the integrated circuit.

Likewise every embedded integrated circuit can only be used for the process for which it was programmed. Generally a change in the sensors requires reprogramming the embedded software.

DETAILED DESCRIPTION

FIG. 1 is a schematic block diagram of an integrated circuit 100 for controlling sensors, according to an exemplary embodiment of the disclosure. In an exemplary embodiment of the disclosure, integrated circuit 100 includes a wireless interface 110 for communicating wirelessly with a network. Optionally, the wireless interface 110 may communicate over a mobile cellular network (e.g. GSM, LTE) with a WAN, for example the Internet or an intranet. In some embodiments of the disclosure, the wireless interface 110 may support local short range wireless communication protocols to communicate with a Local Area Network (LAN), for example with Wi-Fi, Bluetooth or ZigBee instead of communicating over a mobile cellular network.

In an exemplary embodiment of the disclosure, integrated circuit 100 may include a GNSS receiver 120 for determining a physical location of the integrated circuit 100. In an exemplary embodiment of the disclosure, integrated circuit 100 includes a microprocessor 130 and a memory 150 for controlling the integrated circuit 100. Optionally, memory 150 may include a RAM and/or a ROM for storing and executing basic execution commands to control the integrated circuit 100. Optionally the ROM may include a non-volatile memory such as a flash memory. In an exemplary embodiment of the disclosure, integrated circuit 100 further includes an I/O interface 140 for communicating with sensors 250 and/or a sensor controller 240 (see FIG. 2). Optionally, the sensors 250 and sensor controller 240 may return measurements of physical parameters and/or control activation or deactivation of physical processes, for example activating or deactivating a light, water supply, taking measurements, recording data or other processes. In an exemplary embodiment of the disclosure, the I/O interface supports communicating using one or more communication protocols 160 such as Universal Serial Bus (USB), Universal Asynchronous Receiver Transmitter (UART), Inter Integrated Circuit Bus (I²C), Serial Peripheral interface (SPI), Serial General Purpose Input/output (SGPIO) and/or other protocols. In an exemplary embodiment of the disclosure, integrated circuit 100 is configured to control the sensors by commands from an application 225 (see FIG. 2) on an application server 220 (see FIG. 2) instead of locally by an embedded application. Thus integrated circuit 100 is independent of the sensors connected. Optionally, a power source 170 (e.g. a battery) may be coupled to integrated circuit 100 to allow it to function independent of other elements of a system in which it is deployed. Alternatively or additionally, integrated circuit 100 may draw power from the sensors.

In an exemplary embodiment of the disclosure, integrated circuit 100 is initially configured to automatically connect to application server 220 to receive sensor specific commands from application 225 and is not controlled by an embedded sensor specific application. Optionally, when powered up integrated circuit 100 accesses server 220, for example via a mobile service provider 210 (or via a local Wi-Fi router) to communicate with a network 215 that will provide access to application server 220. The server may be a virtual server, for example a cloud server.

In an exemplary embodiment of the disclosure, integrated circuit 100 is initially configured with a unique identifier (e.g. a MAC number) and/or a unique IP address or domain name of application server 220 to access the application server 220 and identify itself when initially powered up. Integrated circuit 100 may additionally provide its location based on information from the GNSS receiver 120.

In an exemplary embodiment of the disclosure, integrated circuit 100 can be attached to any sensor 250 or sensor controller 240 that can connect electrically with the communication protocols supported by the integrated circuit 100, without preparing embedded software for the integrated circuit 100, thus simplifying preparation of hardware for embedded systems (since no programming is required within the integrated circuit 100). In the current disclosure the term sensor includes sensor controllers and any element that can measure physical properties and/or control physical systems and can communicate electronically with integrated circuit 100. For example a unit that can activate or deactivate machines and/or provide feedback relating to the status of the machines. In an exemplary embodiment of the disclosure, the sensors may include, a micro controller unit (MCU), a memory unit, a short range communication unit (e.g. Bluetooth), an encryption, module, accelerometer, compass, temperature sensor, light sensor, audio recorder, video recorder, speaker and other elements.

FIG. 6 is a schematic illustration of a layout of an exemplary integrated circuit 100 and command formats (610, 620, 630) for accessing various sensor interfaces, according to an exemplary embodiment of the disclosure. In an exemplary embodiment of the disclosure, I/O interface 140 may be attached to microprocessor 130 or a part of microprocessor 130. An exemplary microprocessor includes Cortex STM 32L4 series by Stmicroelectronics LTD. Optionally, the microprocessor 130 or I/O interface 140 may include multiple communication lines 190 each supporting a specific communication protocol 160, for example a few lines supporting each of the following protocols: UART/USART, I²C, SPI and/or other protocols 160.

In an exemplary embodiment of the disclosure, the commands used by application 225 may have a common part 300 (e.g. as explained above regarding FIG. 3) but be different for each communication protocol 160.

Optionally, each light fixture includes an integrated circuit 100 for controlling the light fixture 410. Additionally, each light fixture includes a battery backup to enable communication with the light fixture when there is a power failure, for example integrated circuit 100 can notify application 225 that there is a power failure and that the light fixture 410 cannot be turned on. In an exemplary embodiment of the disclosure, each light fixture 410 includes a light sensor 420 to sense the lighting condition at the location of the fixture. The measurements of the light sensor can be used by application 225 to determine if the light fixture 410 should be turned on. Optionally, each light fixture includes a controllable switch 430 and a bulb 440, wherein the controllable switch can be instructed by application 225 to turn on the light fixture 410. In an exemplary embodiment of the disclosure, application 225 receives the location information and light conditions at each light fixture 410 and determines, which lights should be turned on and which should be turned off, for example to provide light to a specific location for a special event. Optionally, application 225 can turn on selective light fixture 410 depending on the lighting conditions, for example to save power or to turn on certain light fixtures 410 instead of non-functional light fixtures 410. Light sensor 420 may be used to determine if a specific bulb 440 is functional or partially functional so that application 225 may provide a report to a maintenance unit to fix malfunctioning light fixtures 410. Optionally, the report can provide the exact location and status of the light fixture, for example that a specific bulb 440 is blinking or burnt out.

In an exemplary embodiment of the disclosure, application 225 can use information from one location to decide on actions for systems in another location.

Additionally, integrated circuit 100 can be used as a tracking device.

In some embodiments of the disclosure, one of the sensors 250 can be a buffer to store data, to reduce transmissions or combine transmissions to selected time intervals instead of continuously transmitting.

In some embodiments of the disclosure, microprocessor 130 can be programmed to shut down the GNSS receiver 120 or other units of the integrated circuit 100, for example to save power when a unit is not needed. Alternatively or additionally, microprocessor 130 can be programmed to enter a low powered mode automatically when not in use for an extended period.
